I suppose it's an Apple news site, but calling them "Apple chipmaker" is a heavy understatement of how ubiquitous TSMC's chips are. Even without Apple involved TSMC would have its foundries running at full capacity to meet demand. Ignoring geopolitical concerns, TSMC is much more of a "boring" manufacturing company than a tech company. So it's not surprising that Berkshire would invest in it.
